Any helpful tips when replacing o2s? I have a 93 vette thanks

 

Use some penetrating oil to loosen them up before hand and I used the O2 sensor tool to install the new ones. Other then that, I don't remember there being any problems...

Warm the car a up bit to expand the metal. You can use a shorty 7/8" 12 point box to remove it. There is a special O2 wrench you can buy. I got mine a Cromwell tools made especially for GM vette and F bodies. However, the 7/8 will work just fine. Just don't touch the business end of the new sensor with your bare hands when installing.
